Yeah I think I nailed it down, error moved to 5. I made sure this time 5&7 wires to 1&3 4 new spark plugs... went to Misfire on 5. A bad injector would never change cylinders so off to grab a coil.. hopefully I can find one today
Got a new coil in, car started and idled much smoother. It still warning me about rear axle, stabilitrak.. but I will clear codes and leave battery unplugged for 20 minutes and see what I have then. Intermittent Coil problem was elusive. but hopefully solved. Just a heads up for anyone who may ever want to order a coil online. The GM Number has been Superseded...
AC DELCO Coil
Old Part # 12669351 newer part# 12713668
Might be fixed.. the minute I buttoned it back up the sun and nice weather went away and it started raining.. lol hopefully I can drive it later this week...
FINALLY had a chance to actually drive the car tonight, went to a cruise night.. hard to really hit hard since roads are still pretty cold here. But no errors, and ran smooth. I still am perplexed how a coil goes bad just sitting in garage for winter, but if that's what it is not too bad.. hopefully nothing else will arise and it's fixes for the time being. Felt weird without the crazy vibration.. kept waiting for something to go wrong the whole way lol
